Etoposide, epirubicin and carboplatin in hormone-refractory prostate cancer.

Twelve patients with hormone-refractory prostate cancer were treated with combination chemotherapy of etoposide, epirubicin and carboplatin (EEC). At relapse, all patients had metastases to the bone and/or soft tissues. The median number of courses was 3 (range 1-10). Epirubicin was not administered in 6 patients because of heart disease. Three patients (25%) had a partial response and 8 (67%) showed no change. The overall response rate was 92%. Pain relief was observed in 4 patients (44%). Four patients were still alive after a mean observation period of 18 months (range 4-36 months), while 8 died with a mean survival period of 11 months (range 7-15 months). Nausea, appetite loss, and alopecia were observed in some patients. All except one patient experienced bone marrow suppression, 5 of whom were treated with granulocyte-colony stimulating factor. EEC chemotherapy in hormone-refractory prostate cancer is considered to be more effective than other kinds of chemotherapy, whereas it frequently induces bone marrow suppression.
